hello, i just bought a castrol gtx 20w50 in one spare part shop in jln kampung jawa, klang at RM42.00 only. first thing in my mind it must be fakr oil but since so cheap why not just bought it and try for my old 4g13. after that i bring back the left over and compare to my previous left over (same castrol gtx but bought in other shop), from the colour and smell is excatly the same mah.
why they sell so cheap ah, is even cheaper than nasa, hi-rev and many local chapalang brand ?
